Child is in state school, differences in chances to get it at 11+ or 13+ MTS?

[schooling123]

As admissions changed, can only apply for 11+ or 13+. If we register for 13+, then my son would compete with all boys who are coming from prep school,s is it a different competition for 11+?
Thank you

It has to be 11+ otherwise where will your ds go to school for 2 years? The MTS Registrar will guide you.

The 13+ entry ds are being taught CE in their prep schools for years 7 & 8.

Or do years 7 and 8 in a prep school. If a school offers both intakes 11+ is usually the larger one and will include other state school pupils. At 13+ the vast majority, if not all, will be privately educated

It all seems pretty clear on their website. Those entering 13+ from state schools may not be tested in year 8 for humanities, mfl or latin but earlier test is universal. They also seems to anticipate 13+ entrants will mainly be from prep schools.

I see you pm'd me but app does not support a reply. Ime entry at year 9 requires a child to hit the ground running, academically and socially, and gcse options are made almost immediately. 13+ is clearly being aimed at prep school pupils with a small concession on range if subjects tested for state/overseas pupils. A 13+ candidate will be competing against predominantly prep school educated boys even so. 11+ more mixed. The change is more like a pretest /deferred entry. What would be your plan between 11 and 13 otherwise?
